thanks ! yeah i got my ca to 360 with 9 dkh i am dosing daily slowly at a time roughly 25 ppm increments. my dkh is staying stable and my mag is around 1100 ppm exactly where it should be at 360 ppmca.

hopefully in a week or 2 i can get my ca levels around 420 ish and hope for some excellent coraline growth. thanks for all your help its much much appreciated!
